Ontario Paramedic Practice Exam

What is the correct technique for administering MDI salbutamol to a patient?

1. Administer multiple puffs simultaneously

2. Provide on a nebulizer

3. Provide on MDI spray, and allow for four breaths for full inhalation

4. Allow the patient to self-administer

The correct answer is: Provide on MDI spray, and allow for four breaths for full inhalation

The correct technique for administering metered-dose inhaler (MDI) salbutamol involves using the inhaler in a way that maximizes the medication's delivery into the lungs. When using an MDI, it is important for the patient to coordinate taking a deep breath and activating the inhaler correctly. By allowing for four breaths for full inhalation, the patient can effectively draw the medication into their lungs with each breath, enhancing the therapeutic effect of the salbutamol. Taking deep, slow breaths helps deliver the medication deeper into the airways, where it can exert its bronchodilator effects most effectively. Using a nebulizer, while it delivers a similar medication, is a different method that isn't compatible with the question asking specifically about MDI administration. Self-administration is a valid approach but should be guided closely for optimal technique, especially in a clinical setting. Multiple puffs simultaneously could lead to less effective medication delivery, as it may overwhelm the patient's ability to inhale the medication properly in a coordinated manner.
